Don't feel bad. This is very familiar to me. It happened in our Petsense, but if we go to Petsmart it will be the same thing. They will be acting like wild animals. Kirby, my bichon loves every human being so she will be trying to kiss and love them up. Khloe, my yorkie is a protector. She wants her toys or treats and no people please!. They are polar opposites. One is charging for the people and the other is charging for the toys! I am trying to manage both of them. My daughter is looking like she belongs to another family , leaving me with two crazy dogs.
